Last Updated: March 17, 2026

These Terms of Service ("Terms") govern your use of MindCal (the "Service"), operated by Keith Meyer ("we," "us," or "our"). By accessing or using MindCal, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. Service Description

MindCal is an AI-powered life management platform that helps individuals and families manage their calendars, email, travel, shopping, contacts, and household cognitive load through a conversational AI interface. The Service integrates with third-party platforms (Google, Microsoft, Meta, travel providers, shopping affiliates) to provide a unified management experience.

2. Eligibility

You must be at least 16 years of age to use MindCal. By creating an account, you represent that you are at least 16 years old and have the legal capacity to enter into these Terms. If you are using MindCal on behalf of a household or family, you represent that you have authority to bind all household members who will use the Service.

3. Account Registration and Security

To use MindCal, you must create an account using a valid email address and password, or by signing in with Google. You are responsible for:

• Maintaining the confidentiality of your account credentials
• All activities that occur under your account
• Notifying us immediately of any unauthorized access or security breach

We implement two-factor authentication (2FA) via email verification for account security.

4. Acceptable Use

You agree not to:

• Use the Service for any unlawful purpose or in violation of any applicable law
• Attempt to gain unauthorized access to the Service, other accounts, or computer systems

6. Intellectual Property

The Service, including its design, code, AI models, branding, and documentation, is owned by us and protected by intellectual property laws. You retain ownership of all content you provide to MindCal (calendar events, contacts, messages, etc.). By using the Service, you grant us a limited, non-exclusive license to process your content solely to provide and improve the Service.

7. Third-Party Services

MindCal integrates with third-party services including Google, Microsoft, Meta, Stripe, travel booking providers, and shopping affiliate networks. Your use of these integrations is subject to the respective third party's terms of service and privacy policy. We are not responsible for the availability, accuracy, or practices of third-party services.

Affiliate links and product recommendations may generate commission revenue for MindCal. This does not affect the price you pay for products or services.

8. AI-Generated Content

MindCal uses artificial intelligence (powered by Anthropic's Claude) to generate responses, suggestions, reminders, and delegated messages. AI-generated content:

• May not always be accurate, complete, or appropriate — you should review important information before acting on it
• Should not be relied upon as professional advice (medical, legal, financial, etc.)
• May be sent on your behalf (delegated messages/reminders) only with your explicit approval through our human-in-the-loop system

9. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that the Service will be uninterrupted, error-free, or secure.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, LOSS OF PROFITS, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR ONE HUNDRED CANADIAN DOLLARS (CAD $100), WHICHEVER IS GREATER.
